Abstract

The invention provides a key structure. The key structure comprises a bottom plate, a key cap, scissor feet, a spring, a positioning seat, a first cover body and a second cover body, and the key cap is arranged above the bottom plate. The scissor feet, the spring, the positioning seat, the first cover body and the second cover body are located between the bottom plate and the key cap. The scissor feet abut against the bottom plate and the key cap. The spring abuts against the key cap. The positioning seat is connected with the key cap, the positioning seat is provided with a positioning groove, and a part of the spring is located in the positioning groove. The first cover body is connected with the positioning seat and provided with a through hole overlapped with the positioning groove, and the spring penetrates through the through hole. The second cover body is slidably connected with the first cover body. The second cover body penetrates through the through hole and abuts against the bottom plate, and the other part of the spring abuts against the second cover body and is covered by the second cover body.

Description

technical field [0001] The invention relates to a key structure, in particular to a key structure applied to a keyboard. Background technique [0002] As a common physical input device, a keyboard is widely used in desktop computers, notebook computers or other electronic devices. Generally speaking, the shaft body used in the key structure of the keyboard is usually a mechanical shaft, a rubber dome (rubber dome) shaft or a spring shaft. Taking the key structure using a spring shaft as an example, the spring shaft can be a compression spring, wherein the compression spring The two ends of the spring abut against the keycap and the bottom plate respectively, and most of the remaining parts of the compression spring are exposed outside. Therefore, the button structure using the spring shaft often has the following problems: it is easy to be deflected when pressed by force; the compression spring is easy to be damaged. [0003] How to overcome the above problems has become a...
